Google Authenticator (Android) + Django says Invalid Token even after the Time Sync

I am trying to implement Multi Factor Authentication using django-two-factor-auth and Google Authenticator. But every time I scan the QR Code, it says "Entered token is not valid."

After researching a lot, I've tried following things:

• I've tried downgrading Django version to 1.8
• Google Authenticator Time Correction for Codes (Says it's already synced).
• Changed server's timezone to IST (My local time zone).
• Tried the example app present in django-two-factor-auth (On my local system. Even that's not working!). Tough, their online example App is working (http://example-two-factor-auth.herokuapp.com/).

I am using django 1.9 and latest version of Google Authenticator (Android). I don't what could be the possible reason.

Thanks.

I had the same problem and I fixed it with these steps:

1. In console sudo ntpdate time.nist.gov
2. Change my settings.py to:

LANGUAGE_CODE = 'en-us'
TIME_ZONE = 'America/Argentina/Buenos_Aires' 
USE_I18N = True
USE_L10N = True
USE_TZ = True

I hope to help.
